FIG. 1 is a perspective view showing the appearance of the information processing apparatus according to the embodiment of the present invention. Further, FIG. 2 is a block diagram showing an internal configuration of the information processing apparatus according to the present embodiment.

The information processing device 10 of the present embodiment is, for example, an ID card such as an employee ID card, and is a control unit 11, a display unit 12, a storage unit 13, a network communication unit 14, an acceleration sensor 16, and an angular velocity sensor 17. And have. These components are capable of transmitting and receiving data or signals through the bus to each other.

The display unit 12 is composed of a liquid crystal display (LCD), an organic EL (OLED: Organic Light-Emitting Diode), electronic paper, and the like.

The storage unit 13 is a large-capacity rewritable non-volatile memory (EEPROM or the like) or the like, and stores a plurality of contents displayed on the display unit 12.

The network communication unit (NW communication unit in FIG. 2) 14 is a communication interface including a communication module such as a LAN chip (not shown). The network communication unit 14 is connected to a server or the like via a network such as a public line network, and performs data communication with the server or the like. For example, the content transmitted from the server is received by the network communication unit 14 and stored in the storage unit 13.

The acceleration sensor 16 is a known three-axis acceleration sensor built in the information processing device 10, and detects acceleration in three directions of the X-axis, Y-axis, and Z-axis on the screen of the display unit 12 in three directions. The respective detection signals XS, YS, and ZS indicating the acceleration of are output.

The angular velocity sensor 17 is a known angular velocity sensor built in the information processing device 10, detects a rotation angle around the vertical Y axis on the screen of the display unit 12, and outputs a detection signal HS indicating the rotation speed. ..

The control unit 11 is composed of a processor, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The processor is a CPU (Central Processing Unit), an MPU, an ASIC, or the like. The control unit 11 functions as a control unit 21, a tilt detection unit 22, and a communication control unit 24 when the control program stored in the ROM or the storage unit 13 is executed by the processor. It should be noted that each of the above-mentioned components of the control unit 11 may be configured by a hard circuit, regardless of the operation based on the above-mentioned control program.

The control unit 21 performs overall operation control, but mainly performs display control of the display unit 12. The communication control unit 24 controls the communication operation of the communication unit 14.

The tilt detection unit 22 detects the acceleration of gravity based on the detection signals XS, YS, and ZS of the acceleration sensor 16, detects the direction (vertical direction) V of the acceleration of gravity, and displays the display unit 12 with respect to the vertical direction V. Detects the relationship between the X-axis and Y-axis of the screen.

For example, when the user hangs the strap ST (shown in FIG. 1) of the information processing device 10 around his / her neck and hangs the information processing device 10, the screen of the display unit 12 is omitted as shown in FIG. 3 (A). Wake up vertically. In this case, since the vertical direction V is substantially parallel to the Y-axis of the screen of the display unit 12, the tilt detecting unit 22 detects the substantially vertical direction as the direction of the Y-axis of the screen.

Further, when the user looks at the screen of the display unit 12 of the information processing device 10, he / she holds the information processing device 10 in his / her hand and keeps the screen of the display unit 12 substantially horizontal as shown in FIG. 3 (B). .. In this case, since the vertical direction V is substantially orthogonal to the X-axis and the Y-axis of the screen of the display unit 12, the tilt detecting unit 22 detects the substantially horizontal direction H as the direction of the X-axis and the Y-axis of the screen.

Further, when the user tilts the screen of the display unit 12 around the Y axis of the screen as shown in FIG. 3C, the tilt detection unit 22 has the vertical direction V as the Y axis of the screen of the display unit 12. Since it is substantially orthogonal to the above, the substantially horizontal direction H is detected as the direction of the Y axis of the screen.

Further, the tilt detection unit 22 has a tilt direction K and a tilt angle around the Y axis of the screen of the display unit 12 with respect to the horizontal direction H as shown in FIGS. 3 (C) and 4 based on the detection signal HS of the angular velocity sensor 17. Detect α. Further, as shown in FIG. 4, the inclination detecting unit 22 detects the inclination direction K and the inclination angle α in both the forward direction and the reverse direction of the Y axis.

It is also possible to detect the tilt direction K and the tilt angle α of the screen of the display unit 12 based on the respective detection signals XS, YS, and ZS of the acceleration sensor 16. Further, instead of the acceleration sensor 16, a pendulum type or float type tilt sensor may be used to detect the direction of the screen of the display unit 12.

Here, the display order displayed on the display unit 12 is preset for the plurality of contents stored in the storage unit 13. The display order of each content is set to cyclic, and it is possible to move from the last display order to the first display order, and to move from the first display order to the last display order. be.

The control unit 21 reads the contents of the first display order from the storage unit 13 and displays them on the screen of the display unit 12. At this time, as shown in FIG. 3B, the user views this screen with the screen of the display unit 12 of the information processing apparatus 10 substantially horizontal. Then, (1) when the user tilts the screen of the display unit 12 in the forward direction of the vertical Y axis as shown in FIG. 3 (C), the tilt detection unit 22 tilts the screen in the forward direction of the Y axis of the screen. The tilt direction K and the tilt angle α are detected.

When the tilt angle α is equal to or greater than a preset threshold value, the control unit 21 displays the content displayed on the screen from the high side to the low side in the tilt direction K of the screen detected by the tilt detection unit 22. Display to gradually erase while moving toward. Then, the control unit 21 reads out the content having the next display order from the storage unit 13, and on the screen of the display unit 12, the empty area (the empty area) in which the previous content is gradually erased and expanded as described above (as described above). In the area where the previous content is not displayed), the read content in the next display order is displayed so as to gradually appear while moving from the high side to the low side in the inclination direction K.

Similarly thereafter, while the tilt angle α and the tilt direction K are maintained, the control unit 21 sequentially reads out a plurality of contents from the storage unit 13, and each of the contents is displayed in the tilt direction K on the screen of the display unit 12. Move from the high side to the low side and display the contents sequentially so that the previous content (the preset display order is the first content) is replaced with the new content (the preset display order is the later content). .. By such control, when the user tilts the screen of the display unit 12 around the forward direction of the vertical Y axis as shown in FIG. 3C, the content displayed on the screen of the display unit 12 is new. It will be displayed after switching to the content.

(2) When the screen of the display unit 12 is tilted in the opposite direction of the vertical Y-axis and the tilt angle α is equal to or larger than a preset threshold value, the tilt detection unit 22 tilts the vertical Y-axis of the screen. The inclination direction K and the inclination angle α around the opposite direction of the above are detected. In the control unit 21, each content moves from the high side to the low side in the tilt direction K on the screen of the display unit 12, and the previous content (content whose preset display order is later) is new content (preset). Display sequentially so that the displayed order is replaced with the previous content). In the case of (2), the moving direction in which the control unit 21 moves and displays each content is opposite to that in the case of (1).

Further, when the tilt angle of the screen of the display unit 12 detected by the tilt detection unit 22 increases, the control unit 21 has the content on the screen of the display unit 12 by the speed corresponding to the increase of the tilt angle. Increase the movement speed of.

Then, when the user returns the screen of the display unit 12 of the information processing apparatus 10 to substantially horizontal and the inclination angle α around the vertical Y axis of the screen detected by the inclination detection unit 22 becomes smaller than the above threshold value, control is performed. The unit 21 stops the movement of the content on the screen of the display unit 12. At this time, when the control unit 21 displays only one content on the screen of the display unit 12, the control unit 21 maintains the display of the content. Further, when the control unit 21 is in a state where, for example, two contents are displayed on the screen of the display unit 12, the control unit 21 selects the content having the larger area to be displayed among the contents, and selects the content. The moving display of the content is continued until only the selected content is displayed on the screen of the display unit 12, and the display is stopped when only the selected content is displayed on the screen of the display unit 12.

For example, it is assumed that the content C1 is displayed on the screen of the display unit 12 as shown in FIG. 5 (A). At this time, once the screen of the display unit 12 is made substantially horizontal and the screen of the display unit 12 is tilted in the forward direction of the vertical Y axis, the control unit 21 controls the display unit 21 as shown in FIG. 5 (B). On the screen of the display unit 12, the content C1 is displayed so as to move from the high side to the low side in the tilt direction K, and at the same time, the next content C2 is moved from the high side to the low side in the tilt direction K. It is displayed, and as shown in FIG. 5C, the content C1 is erased from the screen, and only the next content C2 is displayed on the screen.

Then, when the tilted state of the screen of the display unit 12 is maintained, the control unit 21 moves the content C2 from the high side to the low side in the tilting direction K, as shown in FIG. 5D. At the same time, the next content C3 is displayed so as to move from the high side to the low side in the tilt direction K in place of the content C2, and as shown in FIG. 5 (E), instead of the content C2, the next content C3 is displayed. Only the content C3 is displayed on the screen.

Further, the control unit 21 displays the display unit 12 so as to move from the high side to the low side in the tilt direction K even when the screen of the display unit 12 is tilted in the opposite direction of the vertical Y axis. As shown in A) to (E), the contents C1, C2, and C3 are displayed in the reverse display order and in the reverse direction on the screen of the display unit 12.

Further, as the inclination angle α increases around the vertical Y-axis of the screen of the display unit 12, the moving speed of the contents C1, C2, and C3 on the screen becomes faster.

Further, when the screen of the display unit 12 is returned to substantially horizontal while the content C2 and the next content C3 are both displayed on the screen of the display unit 12 as shown in FIG. 5 (D), FIG. 5 (E). ), The content C3 having the larger display area is selected from the contents C2 and C3, and only this content C3 is displayed on the screen of the display unit 12.

Therefore, various contents can be switched and displayed simply by holding the information processing device 10 in the hand and keeping or tilting the screen of the display unit 12 substantially horizontally. Further, even if the moving speed of the content is fast, each content is gradually switched and displayed, so that the context of the content to be switched and displayed can be grasped and any content can be easily displayed.

Further, according to the present embodiment, when the information processing device 10 is tilted, the display is switched so that each content moves toward the lowered side. Therefore, the user tilts the information processing device 10 to display the display unit 12. You can switch the display screen with the feeling that the content displayed on the screen of is dropped to the lower side in a pseudo manner. Therefore, the user can intuitively understand the operation of switching the display of the content and easily display the content in the following order.

Next, a processing procedure for switching the content displayed on the display unit 12 according to the operation of the information processing apparatus 10 by such a user will be described with reference to the flowcharts shown in FIGS. 7A and 7B.

First, the user hangs the strap ST of the information processing apparatus 10 around his / her neck, hangs the information processing apparatus 10, and turns on the switch of the information processing apparatus 10 to activate the information processing apparatus 10 (S101). When the information processing device 10 is activated, the control unit 21 reads the content C1 in the first display order from the storage unit 13 and displays the content C1 on the screen of the display unit 12 (S102).

In the state where the user hangs the information processing apparatus 10 in this way, the screen of the display unit 12 is raised substantially vertically as shown in FIG. 3A, so that the tilt detection unit 22 is Y of the screen of the display unit 12. Detects a substantially vertical direction as the direction of the axis. In this case, the control unit 21 determines that the screen direction of the display unit 12 is not oriented horizontally (S103 "No"), repeats the process of S103, and the screen direction of the display unit 12 is substantially horizontal. Wait for (maintains the display state of the initial content).

Here, when the user holds the information processing device 10 in his hand and makes the screen of the display unit 12 substantially horizontal, the vertical direction V becomes the X-axis and the Y-axis of the screen of the display unit 12 as shown in FIG. 3 (B). Since they are substantially orthogonal to each other, the tilt detecting unit 22 detects that the directions of the X-axis and the Y-axis of the screen of the display unit 12 are substantially horizontal. In this case, the control unit 21 determines that the direction of the screen of the display unit 12 is substantially horizontal (S103 “Yes”), and around the vertical Y-axis of the screen of the display unit 12 detected by the tilt detection unit 22. The inclination direction K and the inclination angle α of the above are acquired (S104). Then, in the control unit 21, the tilt angle α is the first tilt angle range A (0 ° ≦ α <20 °), the second tilt angle range B (20 ° ≦ α <40 °), and the third tilt angle range C ( It is determined whether it falls within 40 ° ≤ α <60 °) or the fourth inclination angle range D (60 ° ≤ α) (S105, S106, S107, S108).

For example, assuming that the user keeps the screen of the display unit 12 substantially horizontal, the control unit 21 has the tilt angle α around the vertical Y axis as the first tilt angle range A (0 ° ≦ α <20 °). ) (S105 “Yes”), and the content C1 is continuously displayed on the screen of the display unit 12 (S109). Then, when the control unit 21 determines that the tilt angle α around the vertical Y axis continues to be within the first tilt angle range A (S110 “Yes”), the control unit 21 continues the process of S109. Therefore, as long as the user keeps the screen of the display unit 12 substantially horizontal, the display of the content on the screen of the display unit 12 is maintained and the content does not move on the screen. In this case, 20 ° is an example of the above threshold value.

Further, when the control unit 21 determines that the tilt angle α around the vertical Y axis is out of the first tilt angle range A (S110 “No”), the control unit 21 vertically detects the screen of the display unit 12 by the tilt detection unit 22. When the direction of the Y-axis is maintained substantially horizontal (S111 "Yes"), the process from S104 is repeated. That is, as long as the vertical Y-axis direction of the screen of the display unit 12 is maintained substantially horizontal as shown in FIG. 3B or FIG. 3C, the user operation for switching and displaying the content continues. It is assumed that the processing has been performed, and the processing from S104 is repeated.

Then, the user greatly tilts the screen of the display unit 12 around the vertical Y-axis, and the control unit 21 determines that, for example, the tilt angle α around the vertical Y-axis is the second tilt angle range B (20 ° ≦ α <40 °). ) (S105 “No”, S106 “Yes”), the control unit 21 displays the content C1 so as to move from the high side to the low side of the screen of the display unit 12 in the tilt direction K. The content is gradually erased, and the content in the display order corresponding to the forward direction or the reverse direction of the tilt direction K is read from the storage unit 13, and this content is moved from the high side to the low side of the tilt direction K. Is displayed (S112). At this time, the control unit 21 moves each content on the screen of the display unit 12 at a predetermined first movement speed V1 (S113). Then, when the control unit 21 determines that the tilt angle α continues to be within the second tilt angle range B (S114 “Yes”), the control unit 21 continues the processing of S112 and S113. Therefore, while the tilt angle α around the vertical Y-axis continues to be within the second tilt angle range B, the next content is sequentially read from the storage unit 13, and the content is read from the outside of the screen of the display unit 12. It is moved and displayed at the first moving speed V1 to the lower side of the tilting direction K.

Further, when the control unit 21 determines that the tilt angle α around the vertical Y axis deviates from the second tilt angle range B (20 ° ≦ α <40 °) (S114 “No”), the control unit 21 detects it by the tilt detection unit 22. When the vertical Y-axis direction of the screen of the displayed unit 12 is maintained substantially horizontal (S111 "Yes"), that is, when the user operation for switching and displaying the content is continued, S104. Repeat the process from.

At this time, for example, if the user returns the screen of the display unit 12 to a substantially horizontal position, the control unit 21 has the tilt angle α around the vertical Y axis within the first tilt angle range A (0 ° ≦ α <20 °). It is determined that the content is entered (S105 "Yes"), but at this time, if only one content is displayed on the screen of the display unit 12 due to the processing of S112 and S113, the content is displayed on the screen of the display unit 12. The existing content is continuously displayed as it is (S109), and the display of the content is maintained.

Further, if the user returns the screen of the display unit 12 to be substantially horizontal when the two contents are displayed on the screen of the display unit 12 by the processing of S112 and S113, the control unit 21 also performs vertically. Although it is determined that the tilt angle α around the Y-axis is within the first tilt angle range A (S105 “Yes”), the control unit 21 has a display area of each content displayed on the screen of the display unit 12. Selects the content having the larger value, displays only the selected content on the screen of the display unit 12 (S109), and maintains the display of the content.

Then, when the user tilts the screen of the display unit 12 more, the control unit 21 determines that the tilt angle α around the vertical Y axis falls within the third tilt angle range B (40 ° ≦ α <60 °). (S106 "No", S107 "Yes"). Also in this case, the control unit 21 displays the content C1 so as to move from the high side to the low side of the tilt direction K of the screen of the display unit 12 and gradually erases the content C1 and gradually erases the content C1 in the forward direction of the tilt direction K. The contents in the display order corresponding to the surroundings or the reverse direction are read from the storage unit 13, and the read contents are displayed so as to move from the high side to the low side of the tilt direction K of the screen of the display unit 12 (S115). ).

At this time, the control unit 21 moves each content on the screen of the display unit 12 at a predetermined second movement speed V2 (V1 <V2). Then, as shown in FIG. 8A, for example, the control unit 21 sets the moving speed of the content C1 and the content C2 to the second moving speed at the timing when the display of the width portion of the content C1 is erased. Make it faster than V2 (for example, up to twice as fast as V2).

Then, as shown in FIG. 8B, the control unit 21 sets the moving speed of the content C2 to the second moving speed V2 at the timing when the entire content C1 is erased and the entire content C2 is displayed on the screen. The movement speed of the next content C3 is also set to the second movement speed V2 (S116).

Further, when the control unit 21 determines that the tilt angle α continues to be within the third tilt angle range B (S117 “Yes”), the control unit 21 continues the processing of S115 and S116. Therefore, while the tilt angle α around the vertical Y axis continues to be within the third tilt angle range B, the next content is sequentially read from the storage unit 13, and the next content is outside the screen of the display unit 12. The content on the screen is displayed at the timing when the content is moved to the lower side of the tilting direction K at the second moving speed V2 and the display of the width portion of 2/3 of the content in the previous display order is erased. The movement speed becomes faster than the second movement speed V2, the movement speed of the next content becomes the second at the timing when the entire content of the previous display order is erased and the entire content of the next content is displayed on the screen. 2 The movement speed is returned to V2. As a result, switching from one content to the next can be completed more quickly while maintaining the legibility of each content.

On the other hand, when the control unit 21 determines that the tilt angle α around the vertical Y axis deviates from the third tilt angle range B (40 ° ≦ α <60 °) (S117 “No”), the control unit 21 detects it by the tilt detection unit 22. When the vertical Y-axis direction of the screen of the display unit 12 is maintained substantially horizontal (S111 “Yes”), the process from S104 is repeated.

At this time, if the user returns the screen of the display unit 12 to substantially horizontal, the control unit 21 enters the first inclination angle range A (0 ° ≦ α <20 °) with the inclination angle α around the vertical Y axis. (S105 "Yes"), but (i) If only one content is displayed on the screen of the display unit 12, display it on the screen of the display unit 12. The content is continuously displayed as it is (S109) to maintain the display of the content, or (ii) when a plurality of contents are displayed on the screen, the content is displayed on the screen of the display unit 12. Select the content having the larger display area among the existing contents, display only the selected content on the screen of the display unit 12 (S109), and maintain the display of the content. ..

Then, when the user further tilts the screen of the display unit 12 from the state where the tilt angle α is the first tilt angle range A, the control unit 21 has the control unit 21 in which the tilt angle α around the vertical Y axis is the fourth tilt angle range D ( It is determined that 60 ° ≦ α) (S108 “Yes”). Also in this case, the control unit 21 moves the content C1 from the high side to the low side of the tilt direction K of the screen of the display unit 12 so that the display is gradually erased, and the forward direction of the tilt direction K. The contents in the display order corresponding to the surroundings or the reverse directions are read from the storage unit 13 and displayed so as to move from the high side to the low side in the tilting direction K (S118).

At this time, the control unit 21 moves each content on the screen of the display unit 12 at a predetermined third movement speed V3 (V1 <V2 <V3) (S119). Then, for example, as shown in FIG. 9A, the control unit 21 temporarily stops the display of the content C2 at the timing when only the content C2 is displayed on the screen, and immediately after that, FIG. 9 As shown in (B), the content C2 is moved to the lower side of the tilting direction K at the third moving speed V3 and displayed so as to be gradually erased, and the content C3 to be displayed next is displayed from the higher side of the tilting direction K. Starts a display that appears to move to the lower side.

When the control unit 21 determines that the tilt angle α continues to be within the fourth tilt angle range D (S120 “Yes”), the control unit 21 continues the processing of S118 and S119. Therefore, while the tilt angle α around the vertical Y axis is the fourth tilt angle range D, the next content is sequentially read from the storage unit 13, and the content is tilted in the tilt direction K on the screen of the display unit 12. It is displayed so as to move from the high side to the low side at the third movement speed V3, and the display of the content is temporarily stopped at the timing when only the content is displayed on the screen, and then the display of the content is temporarily stopped. The content is displayed so as to move to the lower side of the tilt direction K at the third movement speed V3 and gradually erased, and the content to be displayed next is moved from the higher side to the lower side of the tilt direction K. The display is started. As a result, even if the content is displayed to move at a high speed on the screen of the display unit 12, the user can accurately grasp the state in which only the desired content is displayed.

Further, when the control unit 21 determines that the inclination angle α around the vertical Y axis deviates from the fourth inclination angle range D (60 ° ≦ α) (S116 “No”), the display detected by the inclination detection unit 22 When the vertical Y-axis direction of the screen of the unit 12 is maintained substantially horizontal (S111 “Yes”), the process from S104 is repeated.

At this time, when the screen of the display unit 12 is returned to substantially horizontal, the control unit 21 determines that the inclination angle α around the vertical Y axis falls within the first inclination angle range A (0 ° ≦ α <20 °). Therefore (S105 "Yes"), at the time of this determination, (i) if only one content is displayed on the screen of the display unit 12, the content displayed on the screen of the display unit 12 is used as it is. If the content is continuously displayed (S109) to maintain the display of the content, or (ii) a plurality of contents are displayed on the screen, among the contents displayed on the screen of the display unit 12 Select the content having the larger display area, display only the selected content on the screen of the display unit 12 (S109), and maintain the display of the content.

Further, the user hangs the strap ST of the information processing device 10 around his / her neck, hangs the information processing device 10, and controls the vertical direction V to be parallel to the vertical Y axis of the screen of the display unit 12. When the unit 21 determines that the tilt angle α around the vertical Y axis deviates from the first tilt angle range A, the second tilt angle range B, the third tilt angle range C, or the fourth tilt angle range D ( Since S110 "No", S114 "No", S117 "No", S120 "No"), it is determined that the vertical Y-axis direction of the screen of the display unit 12 is not maintained substantially horizontally (S111). "No"), assuming that the user operation for switching and displaying the content is completed, the process returns to S102.

As described above, in the present embodiment, various contents can be switched and displayed by simply maintaining or tilting the screen of the display unit 12 of the information processing apparatus 10 substantially horizontally without providing a key or a touch panel. .. Further, even if the moving speed of the content is fast, the user can grasp the context of the content to be switched and displayed and easily display any content.

In the above embodiment, as shown in FIG. 9A, the control unit 21 temporarily stops the display of the content C2 at the timing when only the content C2 is displayed on the screen. Immediately after, as shown in FIG. 9B, the content C2 is moved to the lower side of the tilting direction K at the third moving speed V3 and displayed so as to be gradually erased, and the content C3 to be displayed next is displayed in the tilting direction. Although the display that makes the K appear to move from the high side to the low side is started, the following processing may be performed instead.

As shown in FIG. 10A, the control unit 21 temporarily stops the display of the content C2 at the timing when only the content C2 is displayed on the screen, and then shows the content C2 in FIG. 10B. As shown in the above, the content C2 is displayed so as to move in the opposite direction (from the low side to the high side in the tilt direction K) by a certain distance, and then, as shown in FIG. 10C, the content C2 is displayed in the tilt direction K. It may be displayed so as to move from the high side to the low side of. Also in this case, even if the content is displayed to move at a high speed on the screen of the display unit 12, the user can accurately grasp the state in which only the desired content is displayed.

Further, in the above embodiment, the tilt detection unit 22 detects the tilt direction K and the tilt angle α around the Y axis of the screen of the display unit 12 with respect to the horizontal direction, but the tilt direction is different from the horizontal direction. The tilting direction K and the tilting angle α around the Y-axis of the screen may be detected, and the control unit 21 may perform the above-mentioned display control according to the detection result. For example, when the screen of the display unit 12 is held in an arbitrary posture, the tilt detection unit 22 detects the direction of the X-axis of the screen of the display unit 12 with respect to the vertical direction V in response to an operation such as a key. The direction of the X-axis is initially set as a predetermined direction, and then the tilt detection unit 22 detects the tilt direction K and the tilt angle α around the Y-axis of the screen with respect to the predetermined direction.

Further, the information processing device of the present invention can be applied not only to an IC card but also to other types of portable devices.

Further, the configuration of the above-described embodiment described with reference to FIGS. 1 to 10 is merely an example of the present invention, and is not intended to limit the present invention to the configuration.
